The Answer is RIGHT
2
Rules: Write your answer on your board
When the answer is shown give yourself a tally for the correct answer For an incorrect answer, just do not give yourself a tally This game is meant to be a review to help you prepare for the quiz and test PLEASE do not stress and understand the slides will move in a quick pace GOOD LUCK and HAVE FUN
3
Let’s start with some ADDITION
STEPS for ADDING 1) Look at the signs 2) Same signs – ADD example = -7 3) Different signs – SUBTRACT example = 8 remember you take the sign of the larger integer
4
= -7
5
= -111
6
= -0.83
7
-¼ + 6/8 =
8
Everyone’s Fav…. SUBTRACTION
STEPS for SUBTRACTING Change subtraction to addition - 6 – 8 or - 5 – (- 9) 2) Same signs – ADD example = -14 3) Different signs – SUBTRACT example = 4 remember you take the sign of the larger integer
9
+ -3 – (-11) = 8
10
0.3 – 10 = - 9.7
11
-5 – 62 = - 67
12
14 – 122 = - 108
13
Now on to the easier stuff…. MULTIPLICATION
STEPS for MULTIPLYING Positive x Positive = Positive Negative x Positive = Negative Negative x Negative = Positive IN OTHER WORDS… Same Sign = Positive Different Signs = Negative
14
-0.5 × 0.5 = -0.25
15
2 (100) = 200
16
-4 × -1 × -2= -8
17
1.5 or 1½
18
-32 = -3 × -3 9
19
-33 = -3 × -3 × -3 -27
20
Exponent Rules with Negative Integers
Even exponents = POSITIVE Odd exponents = NEGATIVE
21
Last but NOT Least…. DIVISION
STEPS for DIVIDING Positive ÷ Positive = Positive Negative ÷ Positive = Negative Negative ÷ Negative = Positive IN OTHER WORDS… Same Sign = Positive Different Signs = Negative
22
-2 ÷ -5 = 0.4
23
- ¾ ÷ ½ = - 1 ½
24
0 / =
25
Bringing it ALL Together…
Now that we know all the operations we can do multi-step algorithms… Just do not forget… PEMDAS
26
(-5) (-8) + 7 – 17= 30
27
-42 + (-3 – (-12)= 25
28
-2(-2) 2×-2= -16
29
= -132
30
-104
31
5
32
-12
